Easy Plate SA For Staphylococcus aureus

Colonies of Staphylococcus aureus exhibit a clear blue color by using a chromogenic substrate.


1. Easily distinguishable brightly colored colonies at 24 hours

  • Identification is easier compared to agar count media, since the color change makes it unnecessary to confirm the egg-yolk reaction.
  • The incubation time is decreased by half to 24 hours, improving the time to report results.
  • Only one sheet is required when using Easy Plate, while the surface plating method requires three or more plates.

2. High specificity

  • Some S. aureus that exhibit negative egg yolk reactions on conventional agar media can be detected on Easy Plate.
  • Many bacteria other than S. aureus are Inhibited by the selective media. Non-Staph aureus colonies that do develop, are easy to identify due to their pink to red-violet coloring.


3. High correlation with the plate count agar

S. aureus colonies that develop will exhibit a blue coloring making them easy to identify and count. The SA Easy Plate media is inhibitory for other bacteria but, if they develop, they should exhibit a pink to red-violet coloring making discrimination easy.
